Maintenance of Certification

MOC > Diagnostic Radiology


Diagnostic Radiology and Its Subspecialties

IMPORTANT NOTICE: Because Maintenance of Certification requirements and processes for diagnostic radiology and its subspecialties are exactly the same, separate web pages for the subspecialties have been eliminated. The subspecialties include neuroradiology, nuclear radiology, pediatric radiology, and vascular/interventional radiology. If you hold a subspecialty certificate, please refer to the diagnostic radiology web pages for information and requirements.

Please note:

  • You may fulfill the MOC requirements to maintain your certifications in both diagnostic radiology and a subspecialty with a single MOC program. Two separate MOC efforts are not necessary, and fees remain the same.
  • MOC subspecialty exam dates and locations can be found at


Maintenance of Certification (MOC) is for ABR-certified diplomates.

Diplomates who hold TIME-LIMITED certificates, and those with CONTINUOUS CERTIFICATES issued in 2012 and thereafter (with no "valid-through" dates), are automatically enrolled in the MOC program when they attain initial certification and may start participating immediately. 

Diplomates with a SUBSPECIALTY certificate in neuroradiology, nuclear radiology, pediatric radiology, or vascular/interventional radiology also hold either a time-limited certificate or a continuous certificate issued in 2012 and thereafter. They are automatically enrolled in the MOC program and should start participating immediately.

Diplomates who hold LIFETIME certificates must voluntarily enroll in the program to begin the MOC process. Click here for more information.




The ABR's Maintenance of Certification process (ABR-MOC) is designed to facilitate and document the professional development of each diplomate through its focus on the essential elements of quality care.

MOC focuses on the essential elements of quality care.   The American Board of Medical Specialties (ABMS) and the American Board of Radiology (ABR), as a Member Board, have initiated this process. ABR-MOC is a comprehensive vehicle through which all diplomates can ensure the public and the radiologic community that they are incorporating new information into their practices and delivering quality care.


The ABR believes in the value of Maintenance of Certification. All current ABR trustees participate in MOC, as will all future trustees and volunteers.

With that in mind, the ABR highly recommends that all diplomates participate in the MOC program. Those with time-limited certificates, or continuous certificates issued in 2012 or thereafter, are automatically enrolled in the process, though they must initiate their activity. Those with lifetime certificates should consider MOC as an investment that will instill public confidence, demonstrate their commitment to continuing education, and promote the best interests of the patient.



A summary of the six competencies and four parts of Maintenance of Certification can be found here. To view the MOC participation schedule for diagnostic radiology, please see the MOC Participation Guidelines. The Continuous Certification Policy provides detailed guidelines used to evaluate acceptable participation.

A brochure on MOC for Diagnostic Radiology and Its Subspecialties is available here.

NOTE: All diplomates should keep the ABR apprised of any change in contact information or licensure.



MOC Team Tracker is a new online program, developed by the ABR, to assist MOC participants in group practices with their attestation “bookkeeping.” Groups (two or more ABR diplomates) may designate authorized group practice administrators to sign on myABR and manage the input of MOC participation data for the group’s members. More information and instructions for enrolling can be found at

The Whole Practice MOC Discount Pilot Program offers a group-wide discount of 10 percent on the current year’s annual MOC fees. To qualify for the discount in 2014, all eligible participants must be enrolled in MOC, opt in to MOC Team Tracker, and pay all outstanding fees. Further details and requirements can be found at
